From 4b21d0defcc9680da8a694e92d5fe8eb668c2c0b Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Sun, 7 Mar 2010 23:39:01 -0500 Subject: nfsd4: allow 4.0 clients to change callback path The rfc allows a client to change the callback parameters, but we didn't previously implement it. Teach the callbacks to rerun themselves (by placing themselves on a workqueue) when they recognize that their rpc task has been killed and that the callback connection has changed. Then we can change the callback connection by setting up a new rpc client, modifying the nfs4 client to point at it, waiting for any work in progress to complete, and then shutting down the old client.
